$('body').children() puts java applet in incosistent state - opera only

[zeljko]

jQuery: 1.4.4
Browser: Opera 10.63

Problem:

After performing selection with $('body').children(), call to applet method (from javascript) fails with following message: "message: java.lang.NoSuchFieldException: nextSibling".

It appears that .children() method uses sibling() method to move through element siblings, in that method there is a loop: "for ( ; n; n = n.nextSibling )", my guess is that call to n.nextSibling on applet element will try to invoke applet method "nextSibling". It will not fail, but next call to applet method will fail.

This is an issue only in Opera, it seems that it doesn't affect other browsers.

Thanks for taking the time to contribute to the jQuery project by writing a bug report!

Please submit a reduced test case, which reproduces the issue you are experiencing, on  http://jsfiddle.net. So that we can investigate this issue further.

 How to report bugs

It appears to be the problem with opera. It appears that when you call method that doesn't exist on applet opera will not display error message right now but will throw exception on next valid method call.

As stated in my first comment please provide a working test case so that we can investigate this issue, not just an error description.

Also please add information if you are using the <applet> or the <object> tag. If you use the former please check if this still happens if you switch to the object tag as the applet tag is deprecated anyway.
